Assessing risk of bias in studies that evaluate health care interventions: recommendations in the misinformation age.
Page MJ., Boutron I., Hansen C., Altman DG., Hróbjartsson A.
Methods to assess risk of bias in a way that is reliable, reproducible and transparent to readers, have evolved over time. Viswanathan et al. recently provided updated recommendations for assessing risk of bias in systematic reviews of health care interventions. We comment on their recommendations, and discuss new tools in development that we, as co-convenors and coordinators of the Cochrane Bias Methods Group, are leading, which complement the methods recommended.
